"There's something strange going on in Spectrum, South Dakota. Home to high school best friends Jane Langstaff and Heather Meadows, Spectrum is a boomtown that's long since stopped booming, with nothing to show for its former glory but the abandoned Charleswood Estate, Charlesco's dwindling sprocket millions, and the story of the disappeared industrialist who founded the place ... But deep within Charleswood, unbeknownst to anyone, there is a device called the Eidolon, which can open up a door to an otherworldly dimension. And Heather and Jane are about to go knocking" -- Back cover, volume 1.
